IMPROVEMENT IN SUBSOIL-PLOUGHS.-

TO ALL WHOM IT MAY CONCERN: 7

Be it known that we, JOHN VAUGHN, of Miami county, and ELI OHAMNESS, of Grant county, in the State of Indiana, have invented a new and useful Improvement in Subsoil-Ploughs; andwe do hereby declare that the following is a full, clear, andexact description of the construction and operation of the same, reference 'being had to the accompanying drawings, making a part of this specification, in which Figure 1 is a side elevation.

Figure 2 is a front view.

, Like letters in. both figures of the drawings indicate like parts Our improvement relates to that class of excavating-machines used for ploughing up the ground, with a series of spades acting as adjuncts of the plough for a-bctter accomplishment of the san e.

Its nature consists in the combination of a number of spades with a plough and jack, together with framework for supporting and drawing it,'whereby an extremely simple and efl icie'nt article isobtained for the intended purpose.

To enable any one skilled in the art to make and use our invention, we will proceed to describe its construction and operation.

A represents a framework, from which project two angular A-shaped pieces on either side, which are united at their apex, a, and with handles bin the rear for directing and adjusting the machine in position. This frame rests upon an axle, 0,.of the spade-wheel, and has a dash-board, d, on one side thereof, which inclines at a suitable angle towards. and under the rim of the spade-wheel, which dash-board is to prevent the, earth from falling back'into the furrows. I I

p Bis the wheel, whose "axle .rests upon the body or frame. It is three feet in diameter on the wiuest side, sloping inwardly at an angle of forty-five degrees, and about nine inches wide. Attached to the wheel, at the rim e, and'projecting outwardly, is a. series of spades, k, which spades are ten inches'long from point to point, and about-nine inches wide. The spades are attached to the rimof the wheel 0, and to the flange'f thereof,

which strcngthens'and sustains them in position.

represents a jack or cleaner, whose axle is at g, and rests upon the frame or body A, and whose spades are revolved by the motion of those of'the wheel 13 while cleaningthe earth therefrom.

Thcoperation is as follows: The earth, upon being ploughedup by the machine, is immediately thereafter sp'aded, and fully broken up and thrown again uponploughcd ground, but should any earth cling to the spades,

it is cleaned oif by the jack, which greatly facilitates the work. It can he used with or without an ordinary plough. p

To the frame is attached the plough D, which, may be of any style for the work to be performed.

The frame will he made of timber, two and a half by four inches, and three feet wide. 7

Having thus fully described our invention, what we claim therein as new, and desire to secure by Lettcrs Patent, isl 1. The construction and arrangement of the wheel 13, substantially in the manner'and for the purpose as herein set-forth.

2. The combination of.the frame A and dash-boardrt with the wheel 13, substantially in the manner and for the purpose as herein set forth.

l 3. The combination of the plough D with the wheel B, substantially in the manner and for the purpose as herein set forth. I

4. The combination of the jack or cleaner G and frame A with. the wheel B,substantially in the manner and for the purpose as herein set forth.
